Upgrading from Thiel CS3.6 to Avalon


I'm considering upgrading my 20yr-old Thiel CS3.6 to Avalon Opus or Eidolon. Do you guys think it worth the upgrade? My listening room is measuring 17(W)x13(L)x8(H) ft.(speakers along the long wall) Which one(Opus or Eidolon) makes a better choice?
BTW, my other components: Esoteric K-05, Gryphon Diablo, audience Au24e XLR and cables.
Thanks!!

I upgraded from Thiel 3.6 to Ascent ii then to eidolons then to diamond.
Didn't find the 3.6 bright at all. The 3.5 were crazy bright. 3.6s undrivable by anything due to that stupid radiator.
Get ready to switch to some real warm sounding front end.
17x13x8. I recommend
Opus ceramique and add subwoofer.
I have eidolons and diamonds in my small room
A headache to deal with room dampening.
I went from Thiel 3.6 to Avalon Radian HC about 15 years ago. Still have the Avalons if that answers your question.
